43 Claims. 1

This invention relates to registering sheets. It relates to a method of and apparatus for registering sheets to front and side guides as is done preparatory to operating uponthe sheets as, for example, in a printing press or the like. The invention further relates to a method of and means for insuring proper registry of sheets whereby each sheet will be taken by the operating means in proper relationship thereto and successive sheets will be taken in practically identical relationship as toboth position and orientation.

The invention is primarily, although not exclusively, adapted for registering sheets to be taken by the cylinder grippers of a printing press, a cutting and creasing press or the like. Such presses are commonly equipped with feeders which deliver the sheets successively to the drop guides of the press and also side register the sheets whereby to attempt to insure their being properly positioned and oriented before being taken by the cylinder grippers.

One type of feeder to which the present invention may readily be applied comprises means for forwarding sheets successively to the drop guides, side guides and means for. side registering the sheets, i, e., moving them laterally so that a side edge of each sheet lies against a side guide. Ordinarily each sheet is first forwarded until its front edge strikes the drop guides, whereupon it is taken by the side register means and moved laterally into engagement with the side guide, this constituting side registry. Since prior to commencement of side registry the sheet is pre-. sumed to have been registered to the drop guides, any tendency of the side register means to tilt thesheet or move it away from the drop guides results in faulty positioning or orientation of the sheet.

. There is also a tendency for sheets as they move into front registry, i. e., into registry with the drop guides of the press, to bounce back somewhat from the drop uides and in so doing to skew somewhat so that proper registry is disturbed not only with respect to the longitudinal position of the sheets but also with respect to their orientation. So-called register brushe have heretofore been employed in an effort to obviate the tendency of sheets being forwarded to bounce back from the drop guides. These brushes have ordinarily been positioned stationarily a short distance from the drop guides and tilted so that the bristle ends extend somewhat toward the drop guides so that the sheets may pass freely toward the drop guides but so that any attempt of a Such brushes were caused to advance toward the drop guides during side registry of a sheet in an effort to insure accurate simultaneous front registry and side registry. However, such brushes were found to tend to buckle the front edges of the sheets against the drop guides and they also had at times a tendency to disturb proper side registry.

I have devised a method of and apparatus for registering sheets obviating the disadvantages abov pointed out. I provide for registering sheets to-front or dropguides and side guides and insuring proper positioning of each sheet with respect to both sets of guides and also obviating skewing of the sheets resulting in loss of proper orientation. I preferably act upon each sheet as it is bein registered by means frictionally engaging the sheet and moving relatively thereto in a direction at an angl to the direction of advance of the sheet toward the drop guides. I preferably frictionallyengage the sheet and thereby urge it toward the side guide and I find it highly .de-- sirable to simultaneously urge the sheet toward the front guides and toward the side guide. I preferably employ a brush mounted above the feed board or sheet support and movable with I the ends of its bristles in contact with the upper surface of the sheet as the sheet rests upon the feed board. I preferably wing the brush through an are directed generally toward the drop guides and the side guide.

I also provide novel means for mounting and operating the sheet engaging means. Ordinarily the sheet support or feed board is inclined to the horizontal. I provide for mounting and operating the sheet engaging means in such a way as to insure substantially uniform pressure upon the sheet as the sheet engaging means moves thereover, although the sheet engaging means may be mounted to swing about a pivot non-perpendicular to the feed board. I find it preferable to cause the sheet engaging means to operate upon each sheet during side registry of the sheet and it is convenient to employ a portion of the side 3 register means for operating the sheet engaging means.

Other details, objects and advantages of the invention will become apparent as the following description of a present preferred embodiment of the invention and a present preferred method of practicing the same proceeds.

In the accompanying drawings I have shown a present preferred embodiment of the invention and have illustrated a present preferred method of practicing the same, in which Figure 1 is a plan view, with portions broken away, of a sheet feeder arranged for feeding sheets successively to the cylinder of a press;

Figure 2 is a fragmentary vertical longitudinal cross-sectional view, to enlarged scale, of a portion of the feeder mechanism showing the sheet engaging means and its operating mechanism;

Figure 3 is a fragmentary vertical longitudinal cross-sectional view to further enlarged scale of a portion of the mechanism shown in Figure 2; and

Figure 4 is a fragmentary plan view of the mechanism shown in Figure 3.

Referring now more particularly to the drawings, there is shown at 2 the cylinder of a flat bed and cylinder type printing press, which press is provided with the usual drop guides 3. The drop guides are mounted upon a transverse oscillatory shaft 4. Sheets are advanced to the drop guides 3 upon a feed board 5 forming a part of a sheet feeder designated generally by reference numeral 6' and which may be of the type disclosed and claimed in copending application Serial No. 319,862. The sheet advancing or forwarding means constitute no part of the present invention and are not shown in detail. However, such means comprise a pair of oscillatable carriages one of which carries rear suckers l and the other of which carries front suckers 8. The carriages move at all times in opposite directions so that the suckers I move toward the left while the suckers 8 move toward the right and vice versa. The suckers I take a sheet from the solid line position of such suckers in Figure 1 to the chain line position thereof where the sheet is transferred to the suckers 8 when in their chain line position. The suckers 8 then advance the sheet to the solid line position of such suckers when the forward edge of the sheet contacts the drop guides 3, at which time the suckers 3 leave the sheet and move back toward their chain line position in readiness to take another sheet.

Side guides 9 are also provided, there being one such guide at each side of the path of the sheets as they advance toward the drop guides, although only one side guide is employed at any given time. Side register means operate upon each sheet immediately after it has been registered to the drop guides to move the sheet toward the side guide at the side of the feeder toward which the sheet is to be side registered. The side register means is designated generally by reference numeral l and comprises a bracket I l fastened to the feeder frame and carrying a pivot l2. Mounted for pivotal movement about the axis of the pivot I2 is a double bell crank lever I3 having a pair of opposed arms [4 and Ma and an intermediate arm l projecting at right angles to the arms [4 and [4a as shown in Figure 1. Pivoted to the arm [5 at I6 is an operating rod I! which extends transversely of the feeder for operating the means which engage the sheet to effect the side registry thereof. Since such specific means form no part of the present invention they are not illustrated in detail. A link I8 is pivoted to the arm 14 at I9 and is pivoted at to an arm 2| of another bell crank lever which is pivoted to the frame at 22 and has an arm 23 extending substantially at right angles to the arm 2| and carrying a roller 24. The bell crank lever 2l23 is oscillated by any suitable means such as a barrel cam in which the roller 24 rides as shown in Figure 1. Such oscillation is transmitted through the mechanism shown and described to the operating rod H. In the position of the parts as shown the sheets are to be side registered to the side guide 9 which is nearest the bottom of Figure 1. If the sheets were to be side registered to the upper side guide 9 viewing Figure 1 the link I8 would be disconnected from its pivotal connection to the arm l4 at l9 and would be connected to the arm Ma at 28. As the parts are shown in solid lines in all the figures of the drawings a sheet (not shown) has just been registered and the parts are ready to return to their initial position in readiness for registry of the next sheet. The roller 24 in Figure 1 is in its uppermost position viewing that figure and as the barrel cam 25 rotates it moves the roller downwardly which swings the bell crank lever l3 in the clockwise direction about the axis of its pivot I2.

Extending transversely of the feeder is a supporting rod 21. Fastened to such rod in fixed position is a supporting member 28. Such member i in the form of a collar having a bore of such size as to snugly receive the supporting rod 21, a set screw 29 threaded through the member 28 engaging the rod 21 a shown in Figures 2, 3 and 4 to fixedly position the member 28 on the rod. The member 23 has a downward projection 33 to which is fixedly connected at 3! a generally horizontally extending J-shaped bracket 32 shown in plan in Figures 1 and 4. The connection between the member 28 and the bracket 32, although adjustable, is a fixed connection so that the member 28 and the bracket 32 are in effect unitary with each other and with the supporting rod 21.

The J-shaped bracket 32 carries near the end of its shorter leg a Vertical pivot 33 freely rotatable therein. Integral with the pivot 33 is a yoke 34 which rotatably carries a horizontal pivot pin 35. Pivotally carried by the yoke 34 upon the pin 35 and fixed to such pin is a brush carrier 36 carrying a brush 31. The pin 35 extends laterally from the yoke 34, as most clearly shown in Figure 4, and carries adjacent its outer end a collar 38. The collar has a hub portion 39 provided with spaced lots 40 which extend into the hub portion in a direction generally parallel to the axis of the pin 35. A smaller pin 4| passes through the pin 35 and enters certain of the slots 40 in the collar 38 as shown in Figures 3 and 4. Thus the collar 38 is held against rotation relatively to the pin 35, although its rotative position on such pin may be altered at will. A coil spring 42 is coiled about the pin 35 between the yoke 34 and the collar 38 and has one end connected with the yoke and the other end connected With the collar and tends at all times to turn the collar 38 and, consequently, the pin 35 and the brush carrier 36, in the counter-clockwi-se direction about the axis of the pin 35, viewing Figure 3, relatively to the yoke 34. Thus the effect of the spring 42 is to at all time urge the brush 3! toward the feed board 5.

The axi of the vertical pivot 33 intersects the feed board 5 at an acute angle as shown in Figures 2 and 3 since the feed board is"- inclined downwardlyand toward the left viewing such figures. Consequently. the mechanism'thus far explained. mounts the brushfor .swingingmovement about the axis of thepivot 33': in. a gem erally horizontal plane, that is to say,-in a plane intersecting the feed board 5. Connected with the brush carrier .36. and. extending. .upwardly therefrom is a pin 43. Mounted. upon. the. pin 43 and; adapted to be fastened thereto. in desired ad justed position by a set screw 44 is a collar. 45.. Connected with the transversely oscillatory ,operating rod I1 is a fork 416. which. is held. in fixed position on the rod ll .bya setscrew 41. The fork 46 has. two prongs 48 between. which lies the pin 43 as shown in Figures 3. and l. The upper surfaces of the prongs .48. or the fork. 416. are formed as cams .49 extending. upwardly and outwardly away from the the portion of. the fork nearer the rOd IT. The collar 45 rests uponthe upper surfaces of the prongs 48 of the. fork. 46 as shown in Figures 2 and 3. Since the spring 42 tends to swing the brush 31 downwardly toward the feed board 5 about the axis of the pin. 35 the downward movement of the brush is limited by engagement of the collar 45- with the form it.

The operation of the device will now be described. As above mentioned, the suckers i move toward the left, viewing Figure 1, carrying a. sheet by its forward edge, such edge being the a left-hand edge of the sheet viewing Figure 1. When the suckers I reach their chain line position of Figure 1 they transferthe sheet to the sucla ers 8 which are then in their chain line position. The suckers 8 then advance the heet toward the left until such suckers reach their solid line position viewing Figure 1 at which time the forward edge of the heet engages the drop guides Figure'Z, andabout the time the drop guides? 3 rise the grippers take the sheet and carry it around with the cylinder. The sheet is printed as it engages the type bed and. as. its forward edge again. reaches the top of the cylinder it is stripped from the cylinder and, delivered away. as 'well known in the art.

As soon as the sheet has been deposited at the drop guides 3 and released by the suckers 3 as above explained the side register means operates to register the sheet to one of the side guides 9. In the example illustrated in the drawings the sheet is to be registered to the lower side guide 9-, viewing Figure 1. Prior to operation of the side register means the operating rod I1 is in its uppermost position, viewing Figures" 1 and 4, such position being that in which the fork' 46 will assume the chain line position indicated in Figure 4. When the fork is in such position the brush extends at an angle of approximately 45 toward the drop guides and away from the lower side guide 9, viewing Figure 1. When the brush is in such position the collar 45 is in engagement with raised portions of the upper cam surfaces 49' of the prongs 48 of the frame 4'6. Consequently when the brush is inthe position 6 corresponding tothe chain line positionv of Figure4 it is raise'd somewhat from the position shown in Figure 3 the amount of such raising be irig determined by the relationship of the parts and particularly by the shape of the upper sur faces of the prongs of the fork; The. parts are so designed and constructed that as. the brush is swung bythe fork from the position shown in Figure 3 to the position correspondingtothe chain line position of Figure 4 it will rise just enough so that the movement of the brushis substantially parallel to the inclined feed board 5'. Thus the brush will at all times exert a sub stantially constantpre'ssure upon. the feed board and, consequently, upon a sheet lying upon the feed board? l The sheethaving been registered tothe drop guides 3, the operating rod," moves down wardly, viewing Figures 1 and 4, operating; the usual side register means which engage the sheet topull it positively into registry with the. lower side guide 9 viewing Figure 1. However, since the fork 48 is; fixed to the rod l'lsuch fork also move from the chain line position to the full line position of Figure 4, swinging the brush through. an arc of about 45 about the axis of the pivot 33 and so as to tend to sweep the'sheet toward the dropguides 3 and toward the lower side. guide 9 viewing. Figure l. ,The position of the brush 'at the beginning of such swinging movementwis at an angle of approximately 45 toward the drop guides and awayfrom the side guide toward which the sheet is being registered.

As. the brush commences its swinging movement it swings toward both the drop guides and the lower side guide, viewing Figure 1, i. e., the side guide toward which the sheet is being registered. Asthe brush, continues to move it moves less toward the drop guides and more toward the side guide until in its final increment of movement it is moving substantially straight toward the side guide, Thus the brush 3'! frictionally urges the sheet toward the front or drop guides 3 and also toward the side guide .9 to which the sheet is being registered. The brush insures proper registry of the sheet to both the drop guides and the side guide. Likewise the brush prevents bouncing back of the sheet from the drop guides or, if there has been any slight rebounding of the sheet from the drop guides, it urges the sheet back toward the drop guides. to insure that the sheet is properly registered.

After the sheet has thus been registered to the drop guides and the side guide it is ready to be taken by the cylinder grippers and just "before the grippers take the sheet the drop guides 3 rise. to allow the sheet to pass thereunder and follow around with the cylinder to the printing position in engagement with the type bed which reciprocates back and forth below the cylinder. As soon as the sheet has been taken by the the cylinder grippers the operating rod- H moves upwardly, viewing Figures 1 and 4, to prepare for side registry and frictional engagement by the brush 3! of the succeeding sheet. Such upward movement of the rod I! results in swinging of the brush 3'! from the position of Figure 3 in which it is pointing straight down the feed board toward the drop guides to the position corresponding to the chain line position of Figure 41 in which it is pointing at an angle of approximately 45 toward the drop guides and away from the side guide 9 to which the sheets. are being registered. At the same time as the brush swings about the vertical pivot 33- it is also cammed upwardly about the axis of the pin 35 by reason of the fact that as the'fork, 46 moves upwardly,viewing Figure 4, the pin .4 3.moves outwardly along the fork and consequently, en-' gages portions of the upper surfaces of the prongs 48 which are successively higher and higher. As above stated, this results in movement of the brush 31 substantially parallel to the inclined feed board despite the fact that the brush is mounted to turn about the vertical pivot 33.

The pressure of the brush upon the feed board and upon the sheets being fed is regulated by turning the collar 38 upon the pin 35 to apply the desired tension to the sprin 42 nd then by hand adjusting the brush to the desired angular position about the aXis of the pin 35and while holding the brush in such position bringing the collar 45 on the pin 43 into engagement with the upper surfaces of the prongs 48 of the fork 46 and then tightening the set screw 44 to hold the collar 45 in such position. Thus the collar 45 bearing on the fork limits downward movement of the brush but any tendency to move the brush upwardly is counteracted by the spring 42.

Ordinarily it is desirable that the brush 3'! be positioned on the opposite side of the longitudinal center line of a sheet being registered from the side guide to which the sheet is being registered. In Figure 1 the sheets are being registered to the lower side guide 9 and the brush is positioned relatively close to the upper side guide. If the sheets were being registered to the upper side guide the brush would be moved to a position relatively remote from the upper side guide and relatively near the lower side guide. The bracket 32 which, as above described, is of generally J-shape, is designed so that the brush may be swung in either direction. This is to make the bracket and the structure carried thereby universally applicable regardless of which side guide the sheets are being registered to.

As above pointed out, important advantages are obtained by operating upon the sheet frictionally to urge it toward the side guide. The previous attempts to operate frictionally upon sheets by register brushes moved straight toward the drop guides were not successful for reasons above explained. By the use of my sheet registering apparatus as explained proper front and side registry of sheets is insured at all times and the disadvantages of the prior structures are obviated. 7
